There's no reason that controllers need to be complicated at all though. I'd much rather use an empty toy/bb gun scanned into a vr environment for example, and it would be great if all you needed to do that, was scan the object in question. Maybe put a couple of refractive stickers on it, so it's easier to track.

My Vive is coming on Friday(All be it Fedex). Ordered it on the 6th didn't expect it until next month. I'm super excited except that I only have a GTX960. I'm going to spend one night with it then take it over to my friends house who has a 970 to play with it. The release of the 1080 puts me at a little over a week before I can crank everything to high.

Congrats on the vive! What software do you plan to try? I suggest these which I've tried:
Do these first:
-The VR tutorial (it should start automatically after you finish room setup)
-The blu - whale encounter (or the rest too)
-Tilt brush - try writing your name and test all the brushes
-The Lab - Robot repair, Longbow, Slingshot, Xortex (do the other experiments too if you like)

The GTX1080 will definitely be king of the hill for at least half a year, possibly longer, but I'm not so sure it's worth it. The 1070 will likely give 80% of the same performance, and just as good for current generation VR. May not be the case for next gen VR, but by then we'll be close to the next series anyway.

Were you able to run the Vive at all on the 960?

@Firemylaser - Brookhaven is the one I REALLY want to try after seeing how people reacted to it

I have not seen any benchmarks on 1070 yet.. I'm guessing it is the exact same die as 1080, but with some manufacturing flaw, so it is gimped.
That would explain why the 1080 cards ship first, so they can build up stock for the gimped version. /speculation

If you want a great value graphics card for VR I suggest waiting for the AMD Polaris cards likely being released within a month or two. Everything points to a card that is cheaper than 1070, likely $300 or less, but still competes with GTX 980 and the AMD Fury line performance-wise, at least more than enough for VR.

I'm in no rush, both vive and oculus are sold out until July, so the only reason I'd jump on a card now, would be a deal too good to pass up. Seriously sceptical that Polaris can deliver, but we'll see once they're out.
